GEORGE VI MILLER, OF PALISADES PARK, NEIV JERSEY, ASSIGNOR TO MILLER AND HEILMAN, OF NEW YORK, N. Y., A FIRM.

TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 762,182, dated June '7, 1904.

Application filed \pril 20, 1903. Serial No. 153,484. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE W. MILLER, a citizen of the United States, residing at Palisades Park, in the county of Bergen and State of New Jersey, have invented a new and useful Temporary Binder, of which the following is a specification.

This invention is an improved construction of temporary or loose-leaf binder, the object being to provide a cheap and simple device which will open flat when in use, and a still further object is to provide a temporary or loose-leaf binder in which the leaves are se cured at a point adjacent their inner edges and which shall be of such construction that when the device is open the leaves will lie perfectly flat and can be conveniently written upon at a point extremely close to their inner edge.

Another object is to provide a temporary or loose-leaf binder from which a leaf can be extracted at any particular point without removing any of the other leaves of the book.

With the objects in view the invention consists, essentially, in providing a two-part back, such parts being hinged together and having the covers flexibly connected to their outer edges, each section of the back being angular in shape and having plates connected to the oblique portions, each plate having a plurality of curved fingers, each plate also having a plurality of apertures adapted to receive the ends of the opposite fingers, the leaves being held upon the fingers, the sections of the back being provided with spring-catches for the purpose of holding the sections locked together.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a perspective View of a temporary binder constructed in accordance with my invention, the same being shown In carrying out my invention I employ'a back Aand covers B, flexibly connected thereto, said back being made of wood or other suitable material and the covers B of pasteboard or any other suitable material. The back is divided longitudinally into two sections A and A which are hinged together by means of hinges A Each section is angular in shape, the inner face of each back-section being of the form of an obtuse angle, the inner portion A" being straight or flat and the outer portion A being inclined or oblique, as most clearly shown in the drawings. Each back-section has a metal plate O connected thereto, said plate being arranged adjacent the center of the inclined or oblique portion A and each plate has a series of curved fingers D rigidly connected thereto, said fingers being arranged to alternate, as shown in Fig. 4. Each plate also has a series of apertures E, in which the ends of the opposite fingers are adapted to fit when the sections of the back are closed and looked, as shown in Fig. 3, and for the purpose of locking the sections I employ an apertured spring-plate F, which is rigidly attached to one section at the extreme end, the aperture of said plate being adapted to be engaged by a pin G, carried by a spring-plate H, which is secured to the end of the other section, said spring-plate H projecting a sufi icient distance beyond the apertured plate F, as shown at H, to permit the end of the finger or thumb to be pressed thereon for the purpose of disengaging the pin from the aperture, and thereby unlock the sections, so that they can be opened or separated, as shown in Fig. 4, and it will be noted that each back-section is cut away adjacent the end, as shown at A, to provide ample space for the operation of this spring-fastening, it being understood that a fastening is arranged at each end, and'in practice I prefer to have them oppositely disposed that is, at one end the spring-plate F is attached to one section, whereas at the opposite end it is attached to the other section and the spring-plate H correspondin gl y changed.

It will thus be seen that I provide a cheap and simple construction of temporary binder and one from which the leaves can be quickly and easily extracted or inserted when desired. It will also be noted that by having each backsection constructed with an oblique or inclined portion A the leaves can be held perfectly flat when the binder is open, and each leaf can therefore be conveniently written upon very close to the inner margin.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A temporary binder comprising a back consisting of two longitudinal sections, angular in cross-section and hinged together,tl1e covers flexibly connected to the outer edges of the oblique portions of the back-section, a metal 1 plate attached to the oblique face of each backsection, the curved fingers attached to said plates, each plate having openings adapted to receive the ends of the opposing fingers, an
